Forms Thickness Control - Centronics 101 Operator's Manual

FORMS THICKNESS CONTROL
Two adjustment knobs on either side of the print head carriage control the clearance
between the platen and the face of the print head. This clearance must be adjusted according to
the thickness of the forms being used. On a Series 102 printer, the two heads must be adjusted
independently.
To adjust the print head for optimum print quality perform the following steps:
1. Loosen the Lock knob on the left side of the print head.
2. Increase the penetration of the print wires on to the ribbon by slightly turning the
Penetration Control knob.
3. Manually move the print head across the paper. Keep increasing the penetration until
smudging occurs.
4. Back off on the Penetration Control knob just to the point of no smudging.
5. Tighten the Lock knob to secure the print head in position.
Note
Numbers on Penetration Control knob do not
correspond to the number of copies used.
